CANCUN, Mexico (CBS/AP) A judge in Mexico has issued an arrest warrant for former "Survivor" producer Bruce Beresford-Redman, suspected in the killing of his wife while on vacation with their children at a Cancun resort.

Francisco Alor, the state attorney general in Quintana Roo state, said prosecutors would initiate extradition proceedings soon and seek "international collaboration."

Bruce Beresford-Redman has denied any involvement in the April death of his wife, Monica Beresford-Redman.

Police detained the husband briefly and then released him after confiscating his passport and telling him not to leave Mexico.

But Bruce Beresford-Redman returned to Southern California and stated in court documents there that he had been living with his two children for more than a week.

His attorney, Richard Hirsch, said in a statement before the warrant was confirmed that issuing an arrest warrant was a rush to judgment.

"We have been advised that Mexican authorities have issued a warrant for the arrest of Bruce Beresford-Redman," he said. That "is extremely disturbing since it appears that this case is being handled in a manner outside the normal procedures in Mexico."

Hirsch said his client is innocent and is prepared to defend himself in court.

Investigators have said Monica Beresfor-Redman's body showed signs of asphyxiation and evidence of a heavy blow to the right temple. Police said Bruce Beresford-Redman told them he last saw his wife after she left the resort to go shopping and never returned. He reported her missing two days before her body was found.
